Foundational Models (FM) vs Large Language Models (LLM) and AWS Bedrock
Difference Between Foundational Models (FM) and Large Language Models (LLM)
In the field of artificial intelligence, particularly in natural language processing (NLP), two important concepts are Foundational Models (FM) and Large Language Models (LLM). While they share similarities, they serve different purposes and have distinct characteristics.
Foundational Models (FM)
Foundational Models, also known as base models, are large-scale AI models trained on extensive datasets. These models are designed to understand and generate human-like text across a wide range of tasks. Examples include GPT-3, BERT, and PaLM. They are versatile and can be fine-tuned for specific applications but are generally not specialized for any particular task out of the box.

Large Language Models (LLM)
Large Language Models are a subset of foundational models that have been fine-tuned for specific tasks, particularly conversational applications. An example of an LLM is ChatGPT, which is designed to generate human-like text in a conversational context. These models build upon foundational models to provide more context-aware and coherent responses.

What is NLP?
Natural Language Processing (NLP) is a branch of artificial intelligence that focuses on the interaction between computers and humans through natural language. The goal of NLP is to enable computers to understand, interpret, and generate human language in a way that is both meaningful and useful. Applications of NLP include language translation, sentiment analysis, speech recognition, and text summarization.

"An example of an LLM is ChatGPT." Please let me know if I'm wrong, but ChatGPT is a web app, and GPT3 or other versions are LLM. Am I wrong?
